Is it possible to scale F-Curves linearly?
What scaling does depends on your pivot point for that graph editor viewport.  Try this: set your pivot point to 2D cursor.  Open a sidebar in the graph editor.  On the &quot;view&quot; tab, set the cursor location to 0,0.  Then select all and scale by 2.0 in the Y axis.  This will scale all the points about 0,0, which means multiplying all values by 2.  Is that what you want?
(Not at all clear what you expect to happen with your generator.  Again, the x in question here is frame count.  The X is an input, and if it's 201, it's because you're currently looking at frame 201.)
